我们测定了27名口腔内科工作人员的尿汞及他们工作室的汞蒸气浓度。结果表明:口腔内科的工作人员有汞吸收现象。尿汞偏高率达63％,其中护士高于医生,女性高于男性。6个室中有三个室的汞蒸气浓度超过我国现行卫生标准0.01mg/m~3。其中银汞合金调拌室最高。其次是实习进修室。然后我们用定影液代替水储存银汞合金碎屑和余汞。经临床试验,进一步证实对防止诊室汞蒸气污染有一定的效果。使用一个月后,用定影液的诊室汞蒸气浓度明显低于用水储存银汞合金碎屑和余汞的诊室。
We measured urinary mercury levels from 27 oral workers and their laboratory mercury vapor concentrations. The results showed that: staff in the oral medicine mercury absorption phenomenon. Urine mercury high rate of 63%, of which nurses than doctors, women than men. The mercury vapor concentration in three of the six rooms exceeded the current hygiene standard of 0.01 mg / m ~ 3 in our country. Silver amalgam mixing room where the highest. Followed by internship training room. Then we use fixing solution instead of water to store silver amalgam scrap and residual mercury. After clinical trials, and further confirmed to prevent mercury vapor pollution in the office have a certain effect. After one month of use, the mercury vapor concentration in the office where the fixer fluid was used was significantly lower than that of the clinic where silver amalgam crumbs and amalgam were stored with water.
